We have four J2EE engine in productions and we have created JDBC connections on two of those. Both sever JDBC connection failed saying DataSource name already bound. So we deleted datasource and created new with another name. again it fails with same error. It keeps on adding these names in JNDI registry, even if datasource are not there. Now is there a way to remove this names other than server restart as this is a production server we can not restart the server. Please let me know if it can resolved in same way ,or if there are some other issue because of which it is failing.
